The MTW138 is a high-performance industrial grinding mill in the MTW series designed for efficient, large-scale grinding applications with robust construction and advanced features for reliable operation.
The MTW138 has a processing capacity of 6.5 to 18 tonnes per hour (t/h), suitable for medium- to large-scale operations.
The maximum feeding size for the MTW138 is ≤35 mm. Product fineness ranges from 1.6 mm down to 0.045 mm, and can reach about 0.038 mm under optimized conditions.
The overall dimensions are 10,920 × 9,470 × 10,227 mm (L × W × H) and the machine weight is approximately 34 tonnes.
Key power ratings (kW) for MTW138 components are: main unit 90 kW; classifier 18.5 kW; blower 110 kW; crusher 22 kW; bucket elevator 40 kW; electro-vibrating feeder 0.2 kW.
The MTW138 is suitable for building materials, energy and mining industries, and other sectors requiring industrial-scale grinding and powder production.
Core components include the main engine, bearings, and motors. The machine also integrates a classifier, blower, crusher, bucket elevator and electro-vibrating feeder as part of the system.
An installation engineer guide is provided and engineers are available to service machinery overseas. Lifelong spare parts supply is offered along with timely after-sales service.
The MTW138 uses an inner thin oil lubrication system that provides lubrication between the main bearing and drive bearing without an additional lubrication pump, simplifying maintenance.
The mill features wear-resistant volutes to improve material flow and reduce air loss, and a split-design curved surface shovel (blade) so only the blade needs replacement during maintenance, extending component life and reducing downtime.
A high-efficiency precision classifier with unique airtightness ensures consistent product quality, and an isolated cyclone collector enhances classifying efficiency and accuracy.
Yes — the bevel gear overall drive provides higher transmission efficiency and easy installation and adjustment, helping reduce setup time and maintenance complexity.
The MTW138 requires a sturdy foundation capable of supporting ~34 t, adequate space for its 10.92 × 9.47 × 10.227 m footprint and associated auxiliary equipment, proper power supply matching component kW ratings, and dust/ventilation arrangements per local regulations.
Yes — the manufacturer provides lifelong spare parts supply and offers timely after-sales support, including overseas engineer service when needed.
